[PATCH] selftests/powerpc: Fix load_unaligned_zeropad build failure

[Michael Ellerman]

This test is userspace code, but uses some kernel headers via symlinks,
and mocks other headers, in order to test load_unaligned_zeropad().

Currently the test fails to build with:

  In file included from load_unaligned_zeropad.c:26:
  word-at-a-time.h:7:10: fatal error: linux/bitops.h: No such file or directory
      7 | #include <linux/bitops.h>

This is due to the recent changes to the kernel headers.

Fix it by symlinking the new wordpart.h, and creating an empty stub for
bitops.h which is all that's needed.

Kees, do you mind taking this one via your tree because that's where the commit
that changes the headers is?
